They're building these things like mad in my neighborhood. I live in Gilbert, a suburb of Phoenix. One opened in Chandler a couple of months ago, and one is nearly done in Gilbert. There are two or three in Mesa. All of these are within 10 miles of my house. Ten years ago, the only place I saw Sonics was in the boonies in TX.
I don't know about the ice, but my wife goes nuts for the Cherry Lime Ade.
